It doesn't fix it for me, and it's not working in FireFox either these days. After you click in the lower graph, the highlighted area follows the mouse pointer, but never releases even after clicking again, moving away etc. and the upper graph does not update.

@Chris I would start a new question if it's pertaining to a specific Firefox version, the versions mentioned here are ancient history, so I don't know if it's even the same bug.

Hi @jonsca - It's not, it's happening in latest versions of Chrome and Firefox - though not IE10 amazingly!! ;-) - I didn't want to 'clutter' Meta, but if you still think I should open a new question I will do?

@Chris Works fine for me in FF 20. You are highlighting along the bottom graph and not the top one?

(even with the zoom on, it still works, seemingly)

@jonsca Yes, I am clicking on the bottom graph. FF 20.0.1 and Chrome 26.0.1410.64 on Windows 7 64-bit. I've just tried some other profiles (including yours) and same broken behaviour on all.

@Chris I'd say go ahead and post a new question and reference the fact that you've tried the approach in this one and it's not working.
